Description
Technical field
The invention belongs to field of electromechanical technology, more particularly, to a kind of diesel engine air inlet system.
Background technique
Diesel combustion temperature is lower, radiates less, so working under cold environment, takes a long time ability
Cooling water temperature is set to rise to normal temperature.
In vehicle initial stage driving process, the excessive heat dissipation of intercooler keeps diesel engine intake temperature too low, is unfavorable for diesel oil
The promotion of machine operating temperature.
Summary of the invention
In view of this, the present invention is directed to propose a kind of diesel engine air inlet system, by changing under diesel engine difference operating condition
The problem of path of diesel engine intake improves in diesel vehicle initial stage driving process, and intercooler excessively radiates.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of diesel engine air inlet system, including diesel engine body, compressor, triple valve, intercooler and ECU, the pressure
Mechanism of qi outlet connects the import of the triple valve, and there are two outlet, one of outlets to connect the intercooler for the triple valve
Import, the intercooler outlet connection diesel engine body on inlet manifold；Another outlet of the triple valve connects
Meet the inlet manifold in the diesel engine body；The triple valve connection ECU, passes through the control of the ECU.
Preferably, in diesel vehicle initial stage driving process, by the control of the ECU, make the compressor with it is described
Inlet manifold in diesel engine body is directly connected to, and pressurized air can be directly entered the inlet manifold of diesel engine, without institute
Intercooler is stated, the excessive heat dissipation of intercooler is avoided；When diesel engine water temperature rises to normal range (NR), by the control of the ECU,
It can make the threeway Vavle switching, be connected to the compressor with the intercooler, the intercooler is made to work, diesel engine is just
Often work.
Compared with the existing technology, present invention has the advantage that
(1) a kind of diesel engine air inlet system of the present invention can be realized and be travelled at diesel vehicle initial stage by the control of ECU
In the process, the air of blower outlet is directly entered diesel engine intake general pipeline, without intercooler, avoids the excessive of intercooler
Heat dissipation problem is conducive to the rapid increase of diesel engine operating temperature.
(2) the configuration of the present invention is simple, it is easy to accomplish.
